Application filed January 11, 1916. Serial No. 71,650.

` To all whom it may concern.'

Be it known that l, JOSEPH BURGHELL, a citizen of the United States,residing at Minden, in the county of Kearney, State of Nebraska, haveinvented a new and useful Harvester-Supporting Attachment for anTractoryand ll do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

,This invention relates to' a tractor harvester and particularly to.improvedl means for supportin Y the harvester in front of the tractor,where y the harvester may be raised and lowered at will by the operator.

' One of the features of the invention is the provi-sion of meanswhereby as the harvester is `raised and lowered, it will be maintainedsubstantially in a lhorizontal plane parallel with the surface of theground.

rlhe invention comprises further features i and combination of parts, ashereinafter set forth, shown in the, drawings and claimed.-

tiorrmay necessitate alterations, falling within the scope of what isclaimed.

ln the drawings: Figure 1 is a view in side elevation of a tractor,showingthe improved combined supporting and raising and lowering meansapplied thereto, for

supporting a harvester' in ldiHerent ad'- )usted positions in front ofthe tractor.

Fig. 2 isa plan view. Fig. 3 is an enlarged detail view of .theharvester supporter and raising and lowering means. Fig. 4 isa detailView through the 'connections between a driven shaft and theconveyerbelts for' handling the grain or the like.v` Fig. 5 is a view'i'n sideelevation of the machine,sh`ow ing the two bars dispensed with, and onlyone bar 3 used, Fig. 6 is a detail perspective view of thestructureshown in Fig. 5.

. 'and pivoted on the rear axle of the tractor Referring more especiallyto the drawings, 1 designates a tractor which maybe of any suitable orconventional construction,

ln practical fields the details of construc- '4aas shown clearly in Fig.3 ofthe drawi ings, to the arms 18 of the bell crank levers 5 and 6.Pivoted at 4 to the forward ends of the bars 3 are bell crank levers 5and 6, the arms 7 of which are secured at 8 to the frame'9 of theharvester. Secured at 10-to both sides ofthe frame'of the vtractor atits :forward end are plates 11, in' the for-i ward ends of which arockshaft 12 is mounted. Secured at 13 by aset screw to one end of the shaft12 torock therewith is a bell crank leverlt. Secured by a set screw 15tothe other end of the rock shaft to move 470 bell crank lever14 and thearm 16 are pro'- 16d extends, which rod161 connects the arms 18 of thebell crank levers 5 and 6 thereby connecting said parts. Connected tothe arm 19 as at 20-of the bell crank lever 14 'is a rod 21, which inturn is pivoted at 22 to a lever 23, which is pivoted at 24: to asegmental rack plate 25 carried by the real' part 0f the tractor.

. rlhe lever 23 is provided with the'usual.`

hand grip 26 having a rod connection 27 to the dog 28. It is to-be notedthat by moving the' lever 23 forwardly upon its pivot the bell crank.lever 14 and thejarm 16 will be rocked to permit the bars 3 and 3a tolower ,upon their pivots, s'othat the har-v vester will be loweredsubstantially in a horizontal plane parallel with the surface of theground. lt is to be noted that by provision of the bars 3 and 3, soarranged and connected as shown to the bell crank levers 5` i and 6, theharvester will be lowered substantially in parallelism with the ground.'A backward movement of the lever A23 will raise .the harvester. rlFhedog 28 coperates with the teeth of the rack plate, to hold the lever 23in different adjusted positions,

'which will hold the harvester indiiferent adjusted positions.

The harvester may be constructed in any suitable or conventional manner,and as an example the harvester is. provided with a' cutting mechanism29, the cutting bar 30 of which is operated from the driven shaft 31through the gear connections 32, 33, shaft 34 and eccentric and rodconnections 35 and 36. lit is also to be noted that the shaft 31operates the conveyors. 37 and 38 through the belt connections 39 and40, to handle the' grain in such a manner asjto carry it to one side ofthe machine and allowed to deposit loo in the field. The shaft 31 has aabout which the belt 42 (which 1n -turn is operated bythe pulley 43.0f.the conventional form of engine 44 of the tractor) op 1 crates, toimpart motion to the shaft 31. i

The invention having been set forth, what is claimed as new and usefulis In combination with a tractor, a harl' vester, a pair of bars,pivotally mounted ings of the tractor, a bell crank lever on saidl rockshaft at one end, an arm fixed to the' rock/shaft, which arm of the rockshaft and pulley 41,

lthrough said elongated 4one'of the arms of the bell crank lever of saidrock shaft having elongated slots, a

transverse rod connecting corresponding upper extremities of thevertical arms of the first bell crank levers and extending slots, meanscarried by the tractor having connections with the other arm .of thebell crank lever of Said rock shaft, to rock said bell crank lever toraise and lower the harvester, lsaid means comprising a lever and a rodconnected to 1 the bell crank lever of said rock'shaft, and a dogandrack for holding said last named between the engine of the tractor andthe harvester for operating the harvester.

In testimony whereof I have'signed my name tothis specification in thepresence of two subscribing witnesses.
